JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 750,279, dated January 26, 1904.

Application filed June 9, 1902. Serial No 110,716. (No model.)

To all whom it may concern:

Be it known that I, RUssELL HARDING, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Journal-Bearing, of which the followingis such afull, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to journal-bearings, and more particularly to that class of bearings used for railway-cars, which consists of a brass resting upon the axle and a key or wedge interposed between the said brass and the journalbox.

In all journal-bearings of the above class heretofore made, as far as I am aware, the key or wedge has rested only on the central part of the brass, so as to allow of relative movement between the brass and the key. The result of this has been that the wear on the brass is uneven and the brasses are often cracked, owing to the springing of the unsupported on s.

The object of my invention is to construct a bearing of the above-described class in which the key will bear upon the brass throughout substantially its entire length and at the same time permit of the necessary movement between the brass and the key or wedge.

In the accompanying drawings, which illustrate one form of journal-bearing made in accordance with my invention, Figure 1 is a vertical longitudinal section through the center of the complete bearing. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is top plan view of the brass. Fig. 4 is a bottom plan view of the key or wedge, and Fig. 5 is an isometric projection of the complete bearing.

Like marks of reference refer to similar parts in the several views of the drawings.

10 represents the key or wedge, and 11 the brass. The brass 11 is made of any suitable metal and has a curved under face 12 for the] reception of the axle. This curved face 12 may be provided with a soft-metal. lining 14 of the usual form, as shown in Figs. 1 and 2. The upper face 15 of the brass 11 is convex throughout the entire length of the hearing.

The sides of the brass 11 are preferably beveled at 16 in the usual manner. The brass maybe provided with a central oil-opening 17. The key or wedge 10 is provided on its under side with a concave surface 18, corresponding with the convex surface '15 of the brass 11 and bearing upon the said convex surface throughout the entire length or substantially the entire length of the brass 11. The key or wedge 10 is also provided with inclines 19, corresponding to the bevels 16 of the brass 11.

I In using my bearing the brass 11 is placed upon the axle in the usual manner and the key or wedge 10 is inserted between the top of the brass and the journal-box. The key 10 bears upon the brass throughout its entire length, and thus causes it to wear evenly and prevents it from cracking. The curved form of the contact between the brassand the key, however, allows the necessary movement between the two parts. It is also evident that whatever the relative position of the key and brass the entire weight of the car is sustained by the cooperating curved surfaces of these parts and that no additional bearing-surfaces are needed to assist in sustaining the weight when movement occurs between the key and brass.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a journal-bearing, the combination with a brass, of a key or wedge, one of said parts being provided with a face longitudinally concave and transversely straight, and the other with a face longitudinally convex and transversely straight, said faces being in contact substantially throughout the length of the bearing.

2. In a journal -bearing, the combination with a brass having an upper face longitudinally convex and transversely straight, of a key or wedge provided with a lower face longitudinally concave and transversely straight, said faces being in contact substantially throughout the length of the bearing.

In testimony whereof I have hereunto set my hand and affixed my seal in the presence of the two subscribing witnesses.
